U.S. Regulators Say ‘Quiet’ Cars Need to Make Noise
The U.S. government has finalized long-delayed rules that will require “quiet cars” like electric vehicles and hybrids to emit alert sounds when they are moving at speeds of up to 18.6 miles per hour to help prevent injuries among pedestrians, cyclists and the blind.
The rules will require automakers to add the sounds to all vehicles by September 2019. The U.S. Transportation Department said it expects the rules would prevent 2,400 injuries a year by 2020 and require the addition of alert sounds to about 530,000 2020 model vehicles.
Federal officials said the rules will cost the auto industry about $39 million annually because automakers must add an external waterproof speaker to comply. The benefits of the reduced injuries are estimated at $250 million to $320 million annually.
NHTSA estimates the odds of a hybrid vehicle being involved in a pedestrian crash are 19 percent higher compared with a traditional gas-powered vehicle.
The rules will also help the blind and visually impaired.
“This is a common-sense tool to help pedestrians, especially folks who are blind or have low vision, make their way safely,” said NHTSA Administrator Dr. Mark Rosekind in a statement.
The rules apply to hybrid and electric cars, SUVs, trucks and buses weighing up to 10,000 pounds and seek to prevent crashes at intersections or when electric vehicles are backing up.
NHTSA originally proposed extending the sound requirements to all vehicles, including motorcycles and larger trucks and buses. At higher speeds, the alert is not required because other factors like tire and wind noise adequately warn pedestrians, NHTSA said.
The rules set minimum sound requirements but do not specify what sounds must be emitted.
